“…When known, suture lines develop long and more or less symmetrical ventral and first lateral lobes while other ones are small.

“…Research conducted in the past several years within the Berriasian Working Group of the International Subcommission on Cretaceous Stratigraphy questions such systematics and correlation. It has been demonstrated that the provincialism of the neocomitid and himalayitid ammonites is higher than previously assumed in the literature, and that homeomorphy has led to erroneous taxonomic interpretations (see Bulot et al, 2014;Frau et al, 2015Frau et al, , 2016aFrau et al, , 2016bFrau et al, , 2016cLehmann et al, 2015). In particular, a re-examination of the Russian literature leads us to challenge the occurrence of western Tethyan-derived ammonites in the 'Ryazanian' deposits, as testified by the systematic re-assessment provided in the present contribution.…”

“…It corresponds to a medium-sized, chambered fragment with morphological (depressed suboval whorl section) and ornamental (periumbilical bullae, ventral weakening) features better match those observed in K.faurieformis. It should be noted that the species macphersoni was considered as a subjective synonym of Ammonites chaperi Pictet, 1867; the type species of the genus LopezicerasFrau et al, 2016a, but the genus should be considered as a junior subjective synonym ofChapericeras Hoedemaeker in Hoedemaeker et al, 2016, due to its later date of acceptance for publication.…”
